Played just a small part of it but i already loved and this is one of my fav games!
The interface is amazing...YOU CAN MOVE THE CAMERA! (Okay, i've never seen a VN that can move the camera like that...)
And i think my favorite characters are Diya (i'm currently playing as her, and she's so cute) and Min-seo
(she is crazy and i also thought she has a boy, but she's still a nice chara).
